Transcript

  • 1. Unit 2. PROPERTIES OF MATTER Francesco Scudellari – Comenius Assistant 2010/2011 Francisco Rodriguez Marín Institute – Osuna (Spain)
  • 2. What is matter ?
    • - Matter is anything that occupies space and can be measured
    • Can you give me some examples of matter?
  • 3. Examples of matter
    • Everything around us is made of matter
    rocks water animals plants planets
  • 4. Properties of matter
    • Two pieces of matter cannot occupy the same space
      • Example: the sun cannot occupy the same place in space as the moon!!
  • 5. Bodies of matter, systems of matter
    • Bodies of matter ( BODY = CUERPO ):
    • Objects having definite limits.
    • Systems of matter:
    • Things with limits that are not precise
  • 6. Which is a body of matter and which a system of matter ? a stone a tree the sea a forest a house a seashell Yourself! (=tú mismo/a) a mountain range BODY (has got definite Ilimits) BODY SYSTEM (doesn’t have precise limits) BODY BODY BODY SYSTEM SYSTEM
  • 7. Extensive properties of matter
    • Extensive properties depend on the amount (=cantitad) of matter present
      • Examples: mass, weight, length, volume
    This cube of stone has mass of 4 kg, a length of 3 cm, and a volume of 27 cm 3 Mass, length, volume depend on the amount of matter present! This cube of stone has mass of 120 kg, a length of 20 cm, and a volume of 4000 cm 3 !!!!!
  • 8. Intensive properties of matter
    • Intensive properties of matter do not depend on the amount (=cantitad) of matter present
    • Examples of intensive properties: density, color, boiling point
    ( to boil = hervir)
  • 9. Example They have different volume, length, mass , etc. But they have the same boiling point (100ºC): BOILING POINT IS AN INTENSIVE PROPERTY! A pan full of water A thermal pool At which temperature does the water in the pan boil? At which temperature does the water in the pool boil? 100ºC 100ºC
  • 10. Matter can be measured
    • Some extensive and intensive properties can be measured
    For example, we can measure properties such as: LENGTH (=longitud) (extensive) VOLUME (extensive) DENSITY (intensive) MASS….. (extensive) Do you understand the verb to measure? Can you translate it in Spanish? TO MEASURE = MEDIR
  • 11. MEASURING LENGTH
    • Length : the distance between two points
      • We use rulers and measuring tape to determine length
    RULER MEASURING TAPE In Europe, what are the most common units of measurement for length?
  • 12. Units of Length:the Ladder Method For example: 15 m = …… cm 1500 Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step
  • 13. 25 Hm = …… m 1 Km = …..…… mm 725 dm = …….. Dam 1,000,000 2,500 7.25 Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step
  • 14. MEASURING AREA
    • Area : the space occupied by two dimensions , length × width
    The area of this rectangle is: 4 × 2 = 8 4 2 What is the unit of measurement for area? Square metres (m ) 2
  • 15. Units of Area 15 cm = …… mm 250 mm = …..cm 13 Km = ……… Dam 2.5 1,500 130,000 2 2 2 2 2 2 Km 2 Hm 2 Dam 2 m 2 dm 2 cm 2 mm 2 ×100 for each step ÷100 for each step
  • 16. MEASURING VOLUME
    • Volume : the total space occupied by a body, length × width × height
    Example: the volume of a fish tank Volume is measured in …………. Cubic metres
  • 17. Units of Volume For example: 12 m = …………. cm 3 3 12,000,000 And 1600 cm = ……… dm 3 3 1.6 Km 3 Hm 3 Dam 3 m 3 dm 3 cm 3 mm 3 ×1000 for each step ÷1000 for each step
  • 18. MEASURING CAPACITY
    • Capacity : the total space occupied by a fluid (another way of measuring volume)
    Example: the capacity of a bottle of Coke or of a fuel tank I am sure you know at least one unit of measurement of capacity. Can you speak its name aloud?
  • 19. One of the most commonly used units of capacity is…. LITRE
  • 20. Units of Capacity KL HL DaL L dL cL mL ×10 for each step ÷10 for each step
  • 21. MEASURING MASS
    • Mass : the amount of matter in a body
      • Measured in grams (g) or kilograms (kg) using a scale
    A scale is not this: A scale is this:
  • 22. Units of Mass Kg Hg Dag g dg cg mg ×10 for each step ÷10 for each step
  • 23. MEASURING DENSITY
    • Density : how concentrated the mass is, mass ∕ volume
      • Example: which object has the higher density, an anvil ( ) or a sponge( ) ?
    ANSWER: the anvil , because its mass is more concentrated! The unit of measurement for density is…. g/cm (grams over cubic centimetres) 3
  • 24. TEMPERATURE
    • Temperature: the degree of hotness or coldness of a body or system; the thermal energy of a body
      • Measured in degrees Celsius (°C), Fahrenheit (°F), and Kelvin (K)
    • How do we measure temperature here in Europe?
  • 25.
    • To measure temperature, in Europe we use……….
    Celsius degrees! (ºC)
  • 26. THE END!
